Valgrind: Difference between revisions

Some aggressive optimizations may yield false errors in Valgrind if they result in unsupported operations, which may occurr in certain mathematical libraries. Since you don't want to diagnose errors in those libraries, but rather errors in your own code, you should compile and link your code against non-optimized versions of the libraries (such as the Netlib implementation of BLAS/LAPACK) that do not use those operations. This is of course only to diagnose issues; when the time comes to run real simulations, you should link against optimized libraries.
